I also forgot my password and birthday, because I filled it in at random. Later, I found my birthday. The method is as follows: Go to psn. Enter the app column, find everyone to accompany me and download it for free, because this is a dating game. After downloading and installing, a series of personal privacy things will appear when I open it, including my birthday. Click on it and you will find the month and date of my registration! But there is no year, you can try one by one, just a few! Then remember, go to psv settings, psn, log off, and forget the password? Click, fill in the birthday date and try again next year! Then, after success, I will send an email to the mailbox to modify the password and give you an address to modify it! Finally logged in! It's done. I only need 10 minutes! Come on, landlord! Let's start now! Ask for adoption!
